Mac OS X 10.5 Leopard Installation Step by Step

At the time of writing this guide, OS X 10.5 Leopard was the current release by Apple. The newest OS by Apple is OS X 10.10 Yosemite. The installation procedure should be relatively the same as previous versions, although, you will need to first create a Yosemite Recovery Disk using this tool.

Install Mac OS X v10.5 Leopard on a new hard drive.

 
Step 1 — Installing Mac OS X 10.5 Leopard 

• Insert a Mac OS X v10.5 Leopard installation disc into your optical drive.
• Hold down the “option” key and restart the computer to bring up the boot option menu.
• To begin the installation, click the install disc icon on the boot option menu.

Step 2 

• When prompted, select your language and click the arrow button to continue.

 
Step 3 

• After the installer loads, you will be greeted by a welcome window.
• Select “Disk Utility” from the Utilities drop down menu.

Step 4 

• Select your new hard drive from the left column in Disk Utility.
• The correct partition table type needs to be set for your hard drive.
  • If it's a brand-new hard drive, it may have no partition type listed.
  • For an Intel-based machine, you should have "GUID Partition Table" listed.
  • For a Power-PC-based machine, you should have "Apple Partition Map" listed.
• If the incorrect partition type is listed, proceed to the next step to delete and re-create the partition. If not, proceed to step 8.
• Warning: Deleting the partition table will erase the entire contents of the drive.

Step 5 

• The following two steps are only necessary if your drive's partition is set incorrectly. Erasing a partition will permanently erase all information stored inside.
• Select the partition on the drive and click the "-" button.
• When prompted, click the "Remove" button to remove the drive's existing partitions.
• Once the partitions have been removed, click the "Options..." button.

Step 6 

• Select the partition scheme required for your machine:
  • Select "GUID Partition Table" for Intel-based machines.
  • Select "Apple Partition Map" for PowerPC-based machines.
• Click "Ok."
• Press the "+" button to add a new partition.
• Press the "Apply" button.

Step 7 

• Click on the “Erase” tab.
• Choose the Volume format (we recommend “Mac OS Extended (Journaled)”).
• Select a name for the drive.

Step 8 

• Type in a name for the drive. Apple names their drives "Macintosh HD" from the factory.
• Click “Erase.”

Step 9 

• A warning window will pop up and ask if you wish to continue with the erasing process.
• Click "Erase" on the warning window that has popped up.

Step 10 

• After erasing is done, quit Disk Utility.

Step 11 

• After quitting Disk Utility, proceed with the installation by clicking the "Continue" button.
• A window will open and ask if you agree to the Software License Agreement.
• Agree to the Software License Agreement by clicking the "Agree" button.

Step 12 

• Make sure the correct hard drive is selected as the installation destination.
• Click "Continue" to proceed with the installation.

Step 13 

• We are now ready to install Mac OS X v10.5 Leopard on the hard drive. Before proceeding to the next step, make sure that all of the installation settings are correct.
• Click "Install" to commence the installation.

 
Step 14 

• The installer will check the source DVD disk before starting the installation process.
• During this step, you will see a "skip" button. It is not necessary to check the disk, and the "skip" button may be used. However, if you have never used your disk before, or haven't used it recently, it is highly recommended you check it.

 
Step 15 

• Leopard will now install onto the hard drive.
• The installation process can range anywhere from a half hour to an hour.

Step 16 

• If you are installing Leopard from a retail disk, please skip this step.
• If you are installing an OEM version of Leopard, you need to install the iLife applications and other software from the Applications Install Disc.

Step 17 

• The installation was successful. Click "Restart" to reboot the computer.
• At this point you are finished with the Mac OS X install.

Mac OS X Leopard should now be freshly installed. Enjoy!

Make an ISO image for Boot Camp from a Windows installation DVD

When installing Windows 7 or Windows 8 using an installation DVD, you might see the message "press any key" or your Mac might restart to OS X.

Create an ISO file from your installation disc

You might not be able to install Windows 7 or 8 if you're using a Windows DVD on a Mac that doesn't have a built-in optical drive. To install Windows on your Mac, create an ISO image of the install disc instead.

1. While started from OS X, insert the Windows installation DVD in an external optical USB drive.
2. After the DVD mounts, open Disk Utility from the Utilities folder (choose Go > Utilities from the Finder).
3. Select the USB optical drive so it's highlighted in the Disk Utility window.
4. Click the New Image icon at the top of the Disk Utility window.
5. Choose DVD/CD master from the Image Format pop-up menu, then choose none from the Encryption menu.
   
   
    
6. Give the new file a name, then click on Save. The Creating image dialog appears with a progress bar. It may take some time to create an image file from your Windows DVD.
7. Once imaging is complete, select the Windows DVD in the disk list, then click the Eject button at the top of the Disk Utility window. 
8. After the DVD ejects, disconnect your external optical drive from the USB port.
9. From the Finder, locate the disk image file you created earlier. Single click on it to select it, then press the Enter or Return key on your keyboard to rename the file. Change the disk image file extension from .cdr to .iso. When prompted, click "Use .iso" to verify this change.
   
   
    
10. Insert a blank USB 2 flash drive that is a least 16GB in size into a USB port on the computer. Boot Camp Assistant uses this drive to store the Windows 8 install media and support drivers during installation of Windows. This flash drive needs to be formatted for the FAT32 file system and must use the Master Boot Record partitioning scheme. Use Disk Utility to check the format of the flash drive before proceeding, and partition or erase the flash drive if necessary.
11. From the Go menu in the Finder select Utilities.
12. Open the Boot Camp Assistant app in the Utilities folder.
13. Click Continue.
14. Make sure the following options are selected (checked) in the Boot Camp Assistant window:
    ✓ Create a Windows 7 or later install disk
    ✓ Download the latest Windows support software from Apple
    ✓ Install Windows 7 or later version
    
    
15. Click Continue.
16. When prompted to select an ISO image, click Choose, then select the ISO image you created.
17. Click Open.
18. When prompted to save Windows drivers by the assistant, select the flash drive you connected as your destination disk.
19. Click Continue.
20. A message appears letting you know that the next step erases and reformats your flash drive. Click Continue to erase the flash drive.
21. A task status dialog appears with a progress bar. Do not disturb your computer during this process. Boot Camp Assistant creates Windows install media on the USB flash drive, and downloads and copies related Windows drivers to the same drive.
22. Next, a prompt appears asking for a password to install the Boot Camp Assistant helper tool. Type in your administrator password and click Add Helper.
23. Follow the onscreen instructions to partition your drive and to install Windows.
    - If you're asked where you want to install Windows 7 or Windows 8, select the BOOTCAMP partition, click Advanced, then click Format.
    - If you're installing Windows 8.1, select the BOOTCAMP partition, then click Format. 

Make sure your device is "removable"

When creating an ISO image or copying drivers to a USB flash drive, make sure the device you're using works as a removable drive. Some devices mount as a fixed storage device and can't be ejected. 

Connect your flash drive or SD Card, then try to eject it from the Finder. If you don't see an option to eject the drive in the Finder sidebar, this device can’t be used to install Windows.
